Unit definitions

What is a month?

For duration conversion the month is treated as an average of 30.4375 days (365.25 ÷ 12), since calendar months vary from 28 to 31 days. This average is suitable for rough estimates such as loan terms or subscription lengths, not exact calendar arithmetic. Use a date calculator for precise month differences.

What is a second?

The second is the SI base unit of time, defined by the hyperfine transition frequency of caesium-133. It is the foundation of all timekeeping and the basis for every other time unit. Sixty seconds make a minute.
